JAMESTOWN, NEW YORK, ASSVIGNOR TO SALISBURY BALL BEA-RING CORPORATION, A CORPORATION or new YORK. I r

. cHUox.

To all whom it may concern 3 I Be it known that I, JAMES WILSON, a subject of the King of Great Britain, residing at Jamestowmin the county of Chautauqua and State of N'ew'York, have invented certain new and useful Improvements in Chucks; of Which the following is a specification, reference being had thereinto the accompanying drawing. 4

This invention relates toimprovements in chucks, the same being especially adapted and constructed for use in holding the raceway rings of ball bearings in such a manner as to permit the grinding and tru'ingthereof one object of the invention being the provision of a mechanism by means of which the bearing ring is readily placed and clamped in position and quickly removed after being operated upon.

A further object of this invention is the provision of a chuck of this type which is composed of a main attaching member, the gripping end of which is provided with one or more resilient sections'having a receptacle so-that the bearing ring maybe readily clamped therein and at the'same' time held in a true position. p

'A still? further object of the invention is the provision of means'mounted for rotation and'for longitudinal movement relative to the main carrying member of the chuck so that the trued ringmay be readily removed from the chuck.

In the accompanvin'g drawings:

Figure 1 is a side elevation of the'complete'chuck. I

Fig. 2 is an elevation looking from the outer end of the chuck.

Fig. 3 isa section taken on line 3*3 of Fig.2. 7

..Fig. 4 is'a section takenon line H of Referring to the drawings'the numeral 5 designates the main" member which as here shown is provided with the attaching threaded portion 6 and with the head 7 This head as here shown is turned to provide the ring receptacle 8 and is further cut by the two partially transverse grooves 9 to provide the clamping member 10. In operation the ring 11 to be trued is fitted within the ring receptacle 8 and the screw 12 is manipulated from the exterior so as to cause the section 10 I Specification of Iie'tters' Pafent.

e305; who moved andclamp" the ring 1 1, this movement being exceedingly slight but suffi'cient to maintain-the ringbll in'place;

In order to provide a means forquickly releasing'the ring or forcing it out of the receptacle S and thus facilitating the operation of the present'ohuck, the-member die provided with the external screw threads" 13 upon whichis mountedthe externally milled operating sleeve 14 which in turn is provided with the semi-dovetailed forwarde-dge 15 for the reception of the r'ng 1'6, which'is' non-rotating and carries the releasing pins 17 that are mounted for longitudinal move ment in the openings 18- of the head 7', said" openings' permitting the pins 1''? to be rojected beyond the base of the receptacle 8' so as to engage the inner edge of the hearing ring 11. p

From the foregoing description it is evi dent that with a chuck of this type the" outer: ball race ring of a' ball bearing is quickly placed in position and clamped therein so as" to bemaintained true.-

In-ord'er to prevent the ring or sleeve 14 from rotating and accidentally unseat-inn the ring 11 during the rotation of the'cliuck,- there is provided a longitudinal recess 19 in the inner face of the sleeve 14 adapted for the reception of the spring projected pin 20, mounted in the radial recess 21 of the memher 5, as clearly shown in Fig. 3.

-,l. A chuck. including a main member having an attaching end and a ring receiving receptacle at the op osite end. said receptacle being provided with a clamping portion, means mounted in the receptacle end for actinguponrto clamp or release the clamping portion thereof, and manually controlled means mounted for longitudinal movement in the carrying member and for extracting an object seated within the receptacle;

2. A chuck. including a main member having an attaching end and a ring' receiving receptacle at the opposite end. said receptacle being provided with a clamping portion,

means mounted in the receptacle end for acting'up'on to clamp or release the clamping portion thereof, manually controlled means mounted for longitudinal movement in the carrying member and for extracting an object seated within the receptacle, and co-' operative means carried by the latter member and the carrying member against accidental movement.

3. A chuck, including atubular member having an attaching end and a ring receiving receptacle at the opposite end, one section of the wall of the receptacle being spaced from the remaining portion thereof so as to form aclamp, a transversely disposed clamp actuating screw mounted in the member and engaging the clamping portion of the wall to control the movement thereof, and manually controlled means mounted for longitudinal movementin the carrying member and for extracting an obiect seated within the receptacle.

t A chuck, including a tubular member having an attaching end and a ring receiving receptacle at the opposite end, one section of the wall of the receptacle being spaced from the remaining portion thereof so as to form a clamp, a transversely disposed clamp actuating screw mounted in the member and engaging the clamping portion of the wall to control the movement thereof. manually controlled means mounted for longitudinal movement in the carrying memher and for extracting an object seated within the receptacle, and cooperative means carried by the latter member and the carrying member against accidental movement.

A chuck. including a main member having an attaching end and a ring receiving receptacle at the opposite end, said receptacle being provided with a clamping portion, means mounted in the receptacle end for acting noon to clamp or release the clamping portion thereof, said carrying member being provided with external screw threads adjacent the attaching end, an internal screw threaded sleeve mounted thereon. said receptacle end being provided with a plurality of longitudinal openings opening into the receptacle, a pin mounted in each opening for longitudinal movement and. a pin carrying member operably con nected to the ring whereby the rotation of the ring imparts longitudinal movement to the pin.

6. A chuck. including a tubular member having an attaching end and a ring receiving lQCGPtdClP at the opposite end, one section of the wall of the receptacle being spaced from the remaining portion thereof so as to form a clamp. a transversely disposed clamp actuating screw mounted in the member and engaging the clamping portion of the wall to control the movement thereof, said carrying member being provided with external. screw'threads adjacent the attaching end, an internal screw threaded sleeve mounted thereon, said receptacle end being provided with a plurality of longitudinal openings opening into the receptacle, a pin mounted in each opening for longitudinal movement, and a pin carrying member operably connected to the ring whereby the rotation of the ring imparts longitudinal movement to the pin.

7. A chuck, including a tubular member having an attaching end and a ring receiving receptacle at the opposite end, one section of the wall of the receptacle being spaced from the remaining portion thereof so as to form a claim). a transversely dis posed clamp actuating screw mounted in the member and engaging the clamping portion ot the wall to control the movement thereof, manually controlled means mounted forlongitudinal movementin the carrying member and for extracting an object seated within the receptacle. said carrying member being provided with external screw threads adjacent the attaching end, an internal screw threaded sleeve mounted thereon, said receptacle end being provided with a plurality of longitudinal openings opening into the receptacle, a pin mounted in each opening for longitudinal movement. and a pin carrying member operably connected to the ring whereby the rotation of the ring imparts longitudinal movement to the pin.

8. A chuck, including a main member having an attaching end and a ring receiving receptacle at the opposite end, said receptacle being provided with a clamping port-ion, means mounted in the receptacle end for acting upon to clamp or release the clamping portion thereof. said carrying member being provided with external screwthreads adjacent the attaching end, an in tern al screw threaded sleeve mounted thereon, said receptacle end being provided with a plurality oi longitudinal openings opening into the receptacle, a pin mounted in each opening for longitudinal movement, a pin carrying member operably connected to the ring whereby the rotation of the ring imparts longitudinal movement to the pin, and cooperative means carried by the carrying member and the internally threaded ring for locking the ring and pins against a cci dental displacement.
